Naoto Miura

Naoto is obsessed with clockwork and often oblivious to his surroundings. Due to this, he is often bullied at school. Naoto prefers automata over humans, this is because automata do not age while humans do. He even called Marie a fleshbag and refused her request to help her fix Kyoto's Core Tower, and only accepted after RyuZU told him that her younger sister is in there.
